Starting Performance Improvement of Line Start PMSM by Reduction of Space Harmonics

Document Type : Original Article

Abstract

Line start permanent magnet synchronous motors possess many attractive features including high efficiency, low
loss,  high  power  factor,  small  volume  and  light  weight.  Also  they  need  no  inverter  for  starting  which  is
economical for many single speed applications such as most fans, pumps and compressors.  Therefore LSPMS
motors  have  been  considered  as  an  alternative  for  induction  motors,  but  the  starting  performance  of  LSPMS
motors  have  been  a  challenging  issue  concerned  by  many  researchers  so  far. Compared  to  Induction  motors,
because of braking torque due to permanent magnets, the winding space harmonics and their negative impacts
on  LSPMS  motors  torque  characteristics  should  be  considered  more  serious.  In  this  paper,  first  the  mmf
distribution of stator winding in the air gap is studied based on Fourier analysis. Then by using an optimization
process,  a  new  stator  winding  has  been  developed,  which  has  a  lower  harmonic  content  in  its  mmf  than  the
conventional  winding.  Finally  the  method  is  applied  to  an  existing  LSPMS  motor  and  its  performance  is
obtained by a finite element analysis.
